Zhang, Tian Li(Faculty of Graduate Studies and Research, University of Regina, 2013-08)

The main purpose of this thesis is to discuss quantum decoherence in the frame-
work of operator algebras. We will define several types of decoherence of quantum
Markov systems based on the original notion introduced by ...

Cui, Bo(Faculty of Graduate Studies and Research, University of Regina, 2015-12)

This thesis presents and develops theorems on separation in the context of free
convexity and matrix convex sets. After presenting a proof of the Hahn-Banach
Separation Theorem, the main work in this thesis is a treatment ...

Dosselmann, Richard Wayne(Faculty of Graduate Studies and Research, University of Regina, 2012-07)

Image quality assessment is a very challenging problem in image processing. Most
image quality metrics are currently based on super cial variations in pixel values,
perceptual models and structural changes. As well, most ...

Mazadi, Zeinab(Faculty of Graduate Studies and Research, University of Regina, 2013-08)

A pattern is a string containing variable symbols and constants. The language of
a pattern is the set of all strings obtained by replacing all variables in the pattern
with non-empty strings. Patterns and their languages ...

Albayyadhi, Maram(Faculty of Graduate Studies and Research, University of Regina, 2013-01)

We study majorization in Rn and some of its properties. The concept of majorization
plays an important role in matrix analysis by producing several useful relationships.
We find out that there is a strong relationship ...

Rahaman, Mizanur(Faculty of Graduate Studies and Research, University of Regina, 2017-06)

This dissertation undertakes the study of quantum delity, a distinguishability
measure in the context of quantum mechanics, from the operator algebraic
viewpoint. The notion of delity provides a quantitative measure ...

Wood, Clifford Tyler(Faculty of Graduate Studies and Research, University of Regina, 2012-12-14)

We present an overview of the main literature regarding *-endomorphisms of the
von Neumann algebra B(H), the bounded linear operators on a separable, in nite-
dimensional Hilbert space H. In doing so, we follow the ...

Mwangangi, Sadia Hassan(Faculty of Graduate Studies and Research, University of Regina, 2012-04)

The purpose of this thesis is to describe in detail the structure of arbitrary operator
systems S B(H), where H is assumed to be of finite dimension, using
Arveson's non-commutative Choquet theory, and to determine the ...

Alzulaibani, Alaa Awad(Faculty of Graduate Studies and Research, University of Regina, 2016-12)

In this thesis, we construct a class of quantum dynamical semigroups, called quasifree
quantum dynamical semigroups, of the von Neumann algebra generated by an
arbitrary Weyl system, with respect to some compatible ...

Bhattacharya, Angshuman(Faculty of Graduate Studies and Research, University of Regina, 2013-11)

The purpose of this dissertation is two fold. Firstly, we prove a permanence result
involving C*-algebras with the weak expectation property. More speci cally, we show
that if is an amenable action of a discrete group ...
